Computation of Bessel and Airy Functions and of Related Gaussian Quadrature Formulae

  • Walter Gautschi


Procedures are described for the high-precision calculation of the modified Bessel function Kν(x), 0 < ν < 1, and the Airy function Ai(x), for positive arguments x, as pre-requisites for generating Gaussian quadrature rules having these functions as weight function.
